Operation

Internal DIP Switches

Internal DIP switch settings determine the operating mode of the RGB 118 and RGB 118 PLUS. Changing the switch settings requires removal of the top and bottom halves of the case as described below.

Opening the RGB 118 or RGB 118 PLUS Case

To open the RGB 118 or RGB 118 PLUS case, remove the screw from the bottom of the case (see Figure 1 on facing page). This enables removal of the top and bottom halves of the case as shown in Figure 2.

Changing a Switch Setting

The switches on the DIP switch module used in the RGB 118 and the RGB 118 PLUS are the slide type (see drawing, Figure 3 on facing page). To change the position of the slide switch, a small screw-driver is used to push (slide) the switch to the desired position (enable or disable).

Setting Internal DIP Switches

Internal DIP switches SW3-1,2, SW4-1, 2, 3 and SW5-1,2 affect RGB 118 and RGB 118 PLUS operation as follows:

SW3-1 SW3-2

3.When setting the RGB 118 for Sync on Green, you must also disconnect the BNC cable from the external “Sync” output of the RGB 118 and RGB 118 PLUS. Otherwise, sync is output on both green and the composite sync output which may cause abnormal levels of green to appear on the presentation display.

4.Monochrome Composite – Use the Green output only.

Operation

Using the SRI (RGB 118 PLUS only)

The SRI feature of the RGB 118 PLUS is used to determine the approximate horizontal and vertical scan frequencies of video and computer monitors. To use the SRI, hold the RGB 118 PLUS with the feet against the face of the monitor and near the center of the screen as shown in Figures 1 and 2 below.

To view the vertical scan frequency, hold the unit so the LCD readout is on a vertical plane (red SRI button is in the uppermost position) as shown in Figure 1. Wait until the green Vertical (V) LED turns on, then push and hold the red SRI button in until a readout is obtained.

To view the horizontal scan frequency, hold the RGB 118 PLUS so the LCD readout is on a horizontal plane (normal viewing) as shown in Figure 2. When the red Horizontal (H) LED turns on, push and hold the red SRI button in until a readout is obtained. Anti-static, anti-glare or EMI coatings on the face of the CRT may prevent the RGB 118 PLUS SRI from displaying the monitor’s scan frequencies properly. Should this occur, an alternate method to obtain a readout is to set the RGB 118 PLUS on top and toward the rear of the monitor as shown in Figures 3 and 4 below. To view the vertical scan frequency using this method, set the RGB 118 PLUS as shown in Figure 3 with the red SRI button toward the rear of the monitor. Press and hold the red SRI button in when the green Vertical (V) LED turns on. To view the horizontal scan frequency, set the RGB 118 PLUS on the monitor as shown in Figure 4. When the red Horizontal (H) led turns on, press and hold the red SRI button until a readout is obtained.

Applications

Applications

Following are possible applications for the RGB 118 and/or the RGB 118 PLUS.

1. As a Sync Stripper

Using an MBC RGBS cable1, the RGB 118 can be used to strip Sync from Green and separate to Green and Composite Sync outputs.

Connect the RGB with sync on green signal to MBC RGBS cable.

Insert the MBC RGBS cable into the 9 pin input of the RGB 118.

Use the video and sync outputs of the interface as normal.

2.Add Sync on Green

The RGB 118 can be used to add either composite or separate Horizontal and Vertical (HV) sync to the green video channel. Use the MBC RGBS cable1 to add composite sync or the MBC RGBHV cable2 to add separate H&V sync.

Connect the RGBS signal to the MBC RGBS cable or the RGBHV signal to the MBC RGBHV cable.

Insert either of the MBC cables into the 9 pin Universal input of the RGB 118.

Use the instructions found on page 2-3 to add sync on green.

Use only the RGB outputs of the interface.

3.As a Sync Combiner

Using the MBC RGBHV cable2 the RGB 118 can be used to combine separate horizontal and vertical sync to composite sync.

Connect the RGBHV signal to the MBC RGBHV cable.

Insert the MBC RGBHV cable into the 9 pin Universal input of the RGB 118.

Use the Sync output of the interface as a composite sync.

4.Mono Composite

The RGB 118 can be used to convert any video signal to monochrome composite while maintaining resolution.

Connect any video signal to the MBC RGBS cable1.

Insert the 9 pin of the MBC RGBS cable into the Universal 9 pin input of the RGB 118.

Use the instructions found on page 2-3 to convert the signal to monochrome composite.

5.Frequency Indicator

The RGB 118 can be used as a Horizontal or Vertical frequency indicator of any monitor.

Simply hold the RGB 118 PLUS up to the face of the monitor glass and hold in the SRI button on the front panel of the interface. The Horizontal and Vertical scan frequencies will automatically be displayed on the LCD. Refer to page 2-5.

Bandwidth - For video amplifiers, bandwidth is a measure of the range of frequencies that make up the components of video character information within which a video amplifier will respond. The frequency range (passband) is usually measured between the half-power (3-dB) points on the video amplifier amplitude output response vs. frequency curve for a wide range of frequencies while maintaining a constant input signal amplitude for each frequency.

CGA - Color Graphics Adapter. Inroduced in 1983, it was IBM's first product to display both color and graphics. An RCA jack above the 9 pin video output connector provides NTSC video. Signal type is TTL, non-interlaced, with Pixel x Line resolution of 640 x 200 and a color palette of 4/16. CGA has a horizontal scan frequency of 15.75 kHz and vertical frequency of 60 Hz.

Data Monitor - A monitor with horizontal scan capability between 15.75-36(42) kHz. Data monitors and projectors are commonly associated with NTSC video, IBM CGA through VGA and Apple/ Macintosh computer input sources.

ECL - Emitter Coupled Logic. ECL signals are high speed digital logic and are mostly found in high resolution CAD/CAM computers and are usually monochrome or black and white. ECL operates in two level states and switches between these states in small increments of time. Bits are: Next/Most/Least Significant. Conversion to analog is required for proper interfacing.

EGA - Enhanced Graphics Adapter. Introduced by IBM in 1984, the EGA card may be configured with dip switch settings to provide an MDA or CGA output signal. Signal type is TTL, non-interlaced with a Pixel x Line resolution of 640 x 350 and a color palette of 16/64. EGA horizontal scan frequency is 21.8 kHz or 15.75 kHz in CGA mode. Vertical frequency is 60 Hz. The EGA card outputs to a 9 pin “D” type connector.

Graphics Monitor - A monitor with horizontal scan capability from 15.75-75 (80) kHz. Graphic monitors and projectors accept input from NTSC Video and CGAVGA, as well as, high resolution computers and CAD/CAM workstations.

ICWK “Internal Computer Wiring Kit” - ICWK kits provide interfacing signals for computers and terminals with no external video display output. Internal video monitor signals are routed externally from the terminal, usually to a 9 pin connector. From the 9 pin connector, a short cable is included with the kit for signal transfer to the interface 9 pin connector input.

MBC “Monitor Break-out Cable” - A cable used to view a local monitor or terminal while simultaneously routing the computer signal to a new source, such as a data projector or monitor. The cable contains a male and female video connector, either piggybacked to each other or provided as a Y type cable.

Peaking - Peaking compensates for mid and high frequency RGB Video Bandwidth response in data monitors and projectors and for signal losses due to cable capacitance. When using the Peak enhancements on the RGB 118 and RGB 118 PLUS interface, please use the following guidelines for proper output settings:

__ Use with all computer frequencies between 15-125 kHz at any cable length.

__ Use with high frequency computers of 36 kHz or higher with cable lengths 75 feet or greater.

Serration - A vertical synchronizing pulse divided into a number of small pulses, each acting for the duration of half a line in a television system. Serrations are used to keep the horizontal oscillator synchronized during the vertical sync pulse interval.

Sync - The synchronization signals or timing pulses which lock the electron beam in step, both horizontally and vertically, with the image signal. Also called Composite Sync, this signal is derived from a composite or combination of horizontal and vertical drives, with some slightly narrowed and delayed pulses, as well as, the addition of equalizing pulses. It is one of the more popular signals used in video systems today and when used is usually accompanied by subcarrier.

TERMINATOR - A resistor at the end of a coaxial cable or line used to match the impedance of the equipment being used. The resistor absorbs signal energy to prohibit signal reflections back to the source. This causes the source equipment to operate as if the line is connected to equipment of equal impedance.

TTL - Transitor to Transitor Logic. Digital type signal, usually 4-5 volts peak to peak. Distance limitation is 6-10 feet. Signal splitting is acceptable. TTL signals are either “ON” or “OFF” and is characteristic of low resolution computers (CGA).

VGA - Video Graphics Array. Introduced by IBM in 1987, VGA is an Analog signal with TTL level separate horizontal and vertical sync. The video outputs to a high density 15 pin 3 row “D” type connector and has a horizontal scan frequency of 31.5 kHz and vertical frequency of 70 Hz (Mode 1, 2) and 60 Hz (Mode 3). The signal is non-interlaced in modes 1, 2, 3 and interlaced when using the 8514/A card (35.5 kHz, 86 Hz) in mode 4. It has a Pixel x Line resolution of 640 x 480 with a color palette of 16/256,000.
